Referring to Figure 3-1, the method includes:

Step 301: Obtain the current driving refresh rate of the driving device.

No longer.

Step 302: Determine whether the driving refresh rate is less than a preset driving refresh rate threshold.

After acquiring the current driving refresh rate of the driving device, the refresh rate adjusting component can determine whether the driving refresh rate is less than a preset driving refresh rate threshold. The driving refresh rate threshold may be f, and the specific value of f may be set according to actual experience. For example, f=30fps (Chinese: number of frames transmitted per second; English: Frames PerSecond), which is not limited in this embodiment of the present invention .

Optionally, the refresh rate adjustment component may compare the drive refresh rate with the drive refresh rate threshold to determine whether the drive refresh rate is less than the drive refresh rate threshold. For example, the refresh rate adjustment component compares f1 with f to determine whether the driving refresh rate is less than the driving refresh rate threshold.

It should be noted that the solution for determining the transmission duration of the first image frame described here is only an example. In practical applications, other solutions may also be used to determine the transmission duration of the first image frame, which is not discussed in this embodiment of the present invention.

Referring to FIG. 3-3 The first image frame F1 transmitted by the device includes valid data 1 to n and invalid data BLANK, the valid data 1 to n are used for image display, the invalid data BLANK is not used for image display, and the transmission duration of the first image frame F1 can be As Δt, after the display device receives the first image frame F1, it can store the valid data 1-n.

Sub-step 3032 , output P first image frames by using an output duration equal to the transmission duration.

After the refresh rate adjustment component determines the transmission duration of the first image frame, it can use an output duration equal to the transmission duration to output P first image frames, so that the display refresh rate of the display device can be adjusted to P of the driving refresh rate of the driving device. times. For example, please refer to FIG. 3-4, which shows a flowchart of a method for outputting P first image frames with an output duration equal to the transmission duration provided by an embodiment of the present invention.

The first transmission rate may be a fixed transmission rate, which may be a point-to-point (English: PointTo Point; referred to as: P2P) interface rate of the display device, and the unit of the first transmission rate may be the same as the unit of the refresh rate of the display device, and the first transmission rate may be the same as the refresh rate of the display device. The value of a transmission rate is not less than the value of the maximum refresh rate of the display device, so as to ensure that the data transmission rate can keep up with the refresh rate of the display device. Optionally, the unit of the first transmission rate may be fps. Under normal circumstances, the refresh rate range of the display device may be 30fps to 150fps (or 30 Hz to 150 Hz), so it can be known that the maximum refresh rate of the display device may be 150fps. , therefore, the first transmission rate may be greater than 150 fps, which is not limited in this embodiment of the present invention.

In this embodiment of the present invention, the first transmission rate may be V _f , and the unit of the first transmission rate V _f may be fps, which can be determined according to the unit of the first transmission rate V _f , and the first transmission rate V _f is adopted. The effective output duration for outputting valid data of one first image frame may be 1/V _f , so the effective output duration for outputting valid data of P first image frames using the first transmission rate may be P/V _f . For example, please continue to refer to Fig. 3-3. Fig. 3-3 takes P=2 as an example for description. The effective output duration of the display device for outputting valid data 1 to n of each first image frame F1 is 1/V _f , therefore, the effective output duration for the display device to output the valid data of the two first image frames F1 is 2/V _f , that is, the effective output duration in FIG. 3-3 is 2/V _f .

It should be noted that the above-described scheme for determining the effective output duration for outputting the valid data of the P first image frames using the first transmission rate is only exemplary, and in practical applications, other schemes may also be used to determine the output P th The valid output duration of the valid data of an image frame is not described herein again in this embodiment of the present invention.

Sub-step 30322: Determine the invalid output duration corresponding to each first image frame according to the transmission duration and the valid output duration.

After determining the transmission duration of the first image frame and the effective output duration for outputting the valid data of the P first image frames using the first transmission rate, the refresh rate adjustment component may determine each first image frame according to the transmission duration and the effective output duration The corresponding invalid output duration. The invalid output duration corresponding to each first image frame is also the duration of outputting invalid data of each first image frame, which is not limited in this embodiment of the present invention.

Optionally, the invalid output durations corresponding to any two first image frames in the P first image frames are equal, and at this time, the refresh rate adjustment component can use the first invalid duration formula to determine the invalid output corresponding to each first image frame. duration, the first invalid duration formula may be: T _balnk1 =[Δt-(P/V _f )]/P; wherein, T _balnk1 represents the invalid output duration corresponding to each first image frame, and Δt represents the driving device to the display The transmission duration for the device to transmit the first image frame, P/V _f represents the effective output duration for outputting the valid data of the P first image frames using the first transmission rate V _f , and V _f represents the first transmission rate. For example, as shown in FIG. 3-3 , the invalid output duration corresponding to each first image frame F1 is T _balnk1 .

Optionally, the invalid output durations corresponding to at least two first image frames in the P first image frames are not equal. In this case, the refresh rate adjustment component can ensure the sum of the invalid output durations corresponding to the P first image frames. Under the premise of being equal to [Δt-(P/V _f )], randomly assign the invalid output duration to each first image frame, and determine the invalid output duration assigned to each first image frame as each first image frame The corresponding invalid output duration. It should be noted that the scheme for determining the invalid output duration corresponding to each first image frame described here is only exemplary. In practical applications, when there are at least two first image frames corresponding to the P first image frames, When the invalid output durations are not equal, the refresh rate adjustment component may also determine the invalid output duration corresponding to each first image frame in other manners, which are not described herein again in this embodiment of the present invention.

Sub-step 30323, according to the invalid output duration and the second transmission rate corresponding to each first image frame, fill invalid data at the end of the valid data of each first image frame to obtain the processed P first image frames.

After the refresh rate adjustment component determines the invalid output duration corresponding to each first image frame, it can fill in the valid data at the end of each first image frame according to the invalid output duration corresponding to each first image frame and the second transmission rate Invalid data are processed P first image frames. The second transmission rate is an output rate of invalid data of the first image frame, and the second transmission rate may be equal to or different from the first transmission rate, which is not limited in this embodiment of the present invention.
